Problems solved by technology
[0003] However, the existing valve actuators cannot realize remote monitoring, and cannot monitor the condition of the valve actuator in real time at any time, and when the valve actuator fails, the fault cannot be judged in time, so that the use effect of the valve actuator is not good. Good, and the utilization rate is reduced, and the existing valve actuators are more laborious in use, thereby increasing the cost and reducing the work efficiency, and the existing valve actuators have a relatively complicated structure, and it is easy to cause internal parts to rub against each other. Some damage to internal parts, which reduces the service life of the valve actuator

The invention discloses a valve actuator capable of achieving remote control. The valve actuator comprises a valve main body, and the top of the valve main body is provided with a first protecting cover; one end of the first protecting cover is provided with a second protecting cover, and a third protecting cover is arranged on the side, far away from the second protecting cover, of one end of thefirst protecting cover; and the bottom of the first protecting cover is provided with a material through pipe, and the top of the first protecting cover is provided with an inner valve rod penetrating through the inner top end of the material through pipe. According to the valve actuator, a first rotating shaft is driven by a motor to rotate clockwise, so that a first gear is driven to rotate clockwise, and a second rotating shaft is driven by a second gear to rotate counterclockwise through cooperation between the first gear and the second gear; thus, a first rolling wheel is driven to rotate clockwise, and a second rolling wheel is driven to rotate counterclockwise; an inner valve rod is driven to move upwards, so that an inner valve is driven to move upwards, and a feeding port communicates with a discharging port; thus, the valve actuator is more labor-saving in use; and the cost is reduced, and the working efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of valve actuators, in particular to a remote controllable valve actuator. Background technique [0002] The valve actuator is the combination of the actuator and the control valve in the automatic control system. Its role in the automation control system is to accept the signal from the regulator or computer (DCS, PLC, etc.), adjust the flow of the process medium according to its position and characteristics in the process pipeline, so that the controlled automation instrument will be controlled during production. within the range required by the process. [0003] However, the existing valve actuators cannot realize remote monitoring, and cannot monitor the condition of the valve actuator in real time at any time, and when the valve actuator fails, the fault cannot be judged in time, so that the use effect of the valve actuator is not good. Good, and the utilization rate is reduced, and the existing valve...
